One evening when she was about 2, Rachel was playing with her little tiny flashlight and she decided that she was Harry Doctor. (This was a conflation of Harry Goes To The Doctor, a book she loved.) She made me say "Ahhh" and looked in my ears. After careful examination, she looked at me very somberly and told me that I had "ear muffets." She then said she needed to look at my throat and proceeded to pull my shirt up. She studied my tum for a while and then told me that I had ear muffets on my tummy, too, and they were hammering and talking to me.
Perhaps we're lucky she's not pre-med.
